When Lord Davos Seaworth arrives in White Harbor to persuade House Manderly to support Stannis Baratheon, the three Freys are already present. Wyman publicly supports the Freys, as the Iron Throne holds hostage his surviving son and heir, Ser Wylis Manderly, at Harrenhal. Wyman fakes Davos's death by having a criminal with similar features executed and his head dipped in tar so the Freys falsely believe him to be Davos.[8] As a reward for proving his loyalty, Queen Cersei Lannister has Wylis returned to White Harbor via Maidenpool.[9]

Wyman later reveals to Davos that Symond had been bribing several of his servants and two knights to spy on the Lord of White Harbor for the Freys. A handmaid of Symond's wife, Betharios, found her way into the bed of Wyman's fool.[8]

Wyman gives Jared, Rhaegar, and Symond palfreys as "guest gifts"[10] when the three Freys depart White Harbor for the wedding of "Arya Stark" to Ramsay Bolton.[8] They disappear while traveling to Barrowton, however, despite the search efforts of Ramsay.[11]
